New concrete barriers and police with automatic rifles shielded the rustic wooden stalls selling mulled wine, grilled sausages and festive decorations, where on Monday a suspected jihadist attacker took 12 lives.
"After an attack like this, it's nice to see that people stay strong and carry on," said one of the visitors, David Ulbricht, a 24-year-old event manager.
